    for "Turn Signal" and ended up with about 25 pages of threads. I guess this is what I get for thinking that I can wire stuff. Anyway, my '53 M38-A1 is a rats nest of wiring. Pretty much everything is on it's own circuit with the lights, electric fan, brake light switch and dash lights powered all the time. I haven't helped the problem much with adding brake lights, parking lights that are spliced into the headlight wires and tail lights. Basically, I have a huge harry mess. Everything works I however. I managed to splice inline fuses on the major circuits, (lights, sending unit, electric fan) but now I'm thinking that it's time to rework some of this wiring stuff. You should see my homemade brakelight switch, built it using garagedoor brackets, ground down washers and locknuts, a return spring connected to a ziptie wrapped around the bolt that holds the bracket for the steering.

    I've been reading some about the little brake light switch on the master cylinder, and I think I have something like that. It is a little 2 pronged thing on the half of the MC that heads to the rear wheels. Is there a way to check if those things work? If I can delete the homemade switch and use the thing on the MC, I might have a fighting chance to get my Spartan Turn signal thing hooked up (thanks Sparky)

    To be honest, I should really just rework the entire thing with a real fuse block. Here is another question, how realistic is it to run power to the ignition, then power from the ignition to a fuse block that can power everything else? Not counting the starter, etc. As it is now, I have about 5 wires trailing out of the back of the ignition and I'm wondering if there is a better way.

    How much beer would it take to get some of you electrical type guys to come down here and help me.. R)

    I don't think you could give me enough :beer: to come do that, if you could you wouldn't like the results. R)

    Re: the brake switch on the MC, put power to it on one side and run a line to the brake lights on the other side. Back up to the wall and see if the lights light when you hit the brakes. Those pressure switches are very simple to replace if they don't work and easy to wire up. Power on one side, brake lights on the other.

    How do you wire up power? Do you just wrap the hot wire to one terminal and the light wire to the other? Are their sometype of fittings that plug onto the switch?

    I'm Googling now..

    Bullet connectors? Or spade connectors? I've seen both, most likely a bullet connector.

    Just put the hot wire on one side and the brake lights on the other.

    I might suggest you invest $5 for a cheap continuity tester. Then clip one to a prong on the switch and touch the other with the tester and step on the brake pedal. The tester should light.
    While you are shopping get an inexpensive volt meter cause you will need it to test circuits.
    Fuse blocks are available many places. I put in a fuse block that is not switched, one that is, and a ground block. I have a LOT of electrical stuff on my CJ!! I have a rewire kit and one day I will rewire the jeep, but for now it works.

    That's not as much fun, but the thought crossed my mind. I do have two multimeters but if I didn't have one I'd be too Dutch to buy one. R)

    Thanks Jim,
    I have a BMW motorcycle and the CJ, so I am trying to keep the CJ running until the winter is over. I plan on doing the wiring next summer. I'll give you a hollar when I get ready to start.

    Hey Jim
    Wanna install my EZ Wiring kit in my Jeepster for me.:D

    Just thought you might need a chance to relax and enjoy yourself.

    Uh-oh, why do I get a bad feeling about this? R)

    The EZ kit is actually pretty easy. Plan on spending half your time planning, half running the wires, and half making the connections.... :shock: R)

    Thanks for the advice.... I was just giving Jim a hard time. I never met anyone that liked wiring. I don't think it'll be that bad.. It looks alot easier, and more compact, that the Ron Francis one I used a few years back in my 2a. It's probably going to take a little time because I have to plan and modify the dash for the new gauges and rewire the steering column before I wire it.

    Hey Jim, I'm closer and my wiring is messy. ;)

    I actually kinda enjoy it too. Rewiring is on the list - but the list never seems to get any shorter. I guess I could be in the garage now instead of e-jeeping :rofl:

    A GM Windshield washer connector works perfectly! Double-spade encased in plastic. Looks like it was meant for our brake light switch. :beer: Got mine at the FLAPS.
